This affected any exoplanet including Proxima b, which was considered as a possible home to extra-terrestial life. The superflare which occurred in on March of 2016 was so bright that it was visible to the naked eye from the Earth. It was observed by the Evryscope, an array of telescopes. funded through the National Science Foundation‘s Advanced Technologies and Instrumentation (ATI) and Faculty Early Career Development (CAREER) programs.
Over the last two years, the Evryscope has recorded 23 other large Proxima flares, ranging in energy from 10^30.6 erg to 10^32.4 erg. Solar flare activity would be one of the greatest potential threats to planetary habitability in a system like Proxima Centauri. In addition stellar flares, quiescent X-ray emissions and UV flux from a red dwarf star can would be capable of stripping planetary atmospheres over the course of several billion years. This and other studies have concluded that any planets orbiting Proxima Centauri would not be habitable for very long, and likely became lifeless balls of rock a long time ago.
